Re: working hours:
yes, it's told at the end of the article.
"A spokesperson for County Durham and Darlington NHS Foundation Trust said: “The calendar was developed and shared internally, during June which is nationally recognised as Pride Month, as part of the work led by our LGBTQ+ staff network, using time allocated through our staff network group framework.
“It is part of a wider programme of activity throughout the year which includes marking a range of national and international recognition days and public awareness campaigns.
“The calendar was intended to be a supportive, optional resource for staff.
“It was shared in a gentle and non-directive way, with no call to action. As an organisation, we are committed to creating a workplace where all colleagues feel safe, supported and respected.”
"with no call to action" - you would hope so, or are they suggesting to lesbian staff that they must become pansexual or polyamorous? (they can, of course, but from their own decision, not because their bosses suggested it). It's so intrusive.
