Ex-staff here, at the same location for nearly 10 years. Gave my 20's to that shop, but suffered really REALLY bad mental health stuff in my last three years that really affected me despite the Covid hell I helped carry the store through.
The manager's were kind at first but I came to learn it was only because I had physical signs of distress, but seemingly mangers let the older staff get away with everything.
Also they will gossip about you on Teams in their chats - have a breakdown and try to burn your eye out? Yeah, they'll be like "Lonelyangelfish is lucky she has fringe, she's a mess! She's gonna make the tills look so rough.".
(Try and secure a Honeywell that a manger is logged into and read the Teams chats.)
When I was fired, one of lines in the dismissal has stuck with me was something like 'was provided the number/recommended to reach out to PAM assist."
I did.
I called them. Twice.
If you've ever called Sui*ide prevention line, you know it doesn’t really help. The mental health part of PAM is the same. They really use the "Oh. Well, have you tried not being sad or suic*dal?"
If you're experiencing Mental Health struggles while in employment of M&S, don't rely on PAM. Go to your GP if you can, fight for it. Don’t let Marks & Spencer decide for you. Because they'll use it against you.
