Like most websites, UNISON’s uses cookies to improve our users’ experience.  We ask when you first access our site if you are happy for cookies to be used. If you choose not to use cookies, it may be difficult to use some parts of our website.

Cookies set by our website are:

  • We use exp_cookies_decline, exp_cookies_allowed or exp_cookies_declined to track and respect your choices. Around all our websites we use cookies to remember where you are and to help and protect you.
  • We use exp_last_activity so every time the page is reloaded the last activity is set to the current date and time. It is used to determine form or login expiry. This is essential for logged in users to record their data and not lose it as it is being input. The expiry time 12 months.
  • exp_last_visit sets the date and time that the you last visited the site. Affects guests and logged in users. The expiry time is 12 months.

  • We also use exp_csrf_token. This cookie protects against Cross Site Request Forgery (CSRF). A CSRF attack forces a logged-on victim’s browser to send a forged HTTP request, including the victim’s session cookie and any other automatically included authentication information, to a vulnerable web application. It expires from your computer after one hour.
  • exp_stashid generates a unique ID that relates to session values that determine the current state of the website and any actions you have performed. Expiry time: session.

Social media buttons

On many of the pages of the site you will see ‘social buttons’, such as share buttons for Twitter, and Facebook ‘Like’ buttons.
When you click on any of these buttons, these sites will be registering that action and may use that information.
You should check the respective policies of each of these sites to see how exactly they use your information and to find out how to opt out, or delete, such information.

External web services

We use a number of external web services on the UNISON site, mostly to display content within our web pages. For example, to display videos we sometimes use YouTube. This is not an exhaustive or complete list of the services we use, or might use in the future, when embedding content, but these are the most common.

As with the social buttons, these sites may use information about usage of embedded content. If you are not logged in to these external services, then they will not know who you are but are likely to gather anonymous usage information e.g. number of views, plays, loads etc.
