new WFH policy one week after signing my contract, kill me

So I've signed my new contract last week to go intern at this company. Not even a week later, they have updated their WFH policy .The new document was released last week (during my holiday). The new WFH-day now has the following rules:

• 1 day a week max
• You'll have to plan in an actual meeting with the teamlead to discuss why/when before the WFH day (and my manager has barely any free slots lmao)
• You need to give a reason
• You need to give a location where you'll be working from home
• You need to have an additional written proof and written approval of this request
• The teamlead needs to have it and HR will actively track it
• HR has the right to overrule the approval of the teamlead
• You cannot ask for a WFH day when you are sick one day in that week, have holiday in that week, have a bank holiday in that week, prolong weekend or other reasons that would 'prolong' your 'holiday'
• You agree that the employer can control your home-office at any time (wtf????)
• You have to work during the office hours so fuck people with flexible hours
• Overwork is still not paid
• Mentioned that reasons like deep concentration is not valid
• It is stated that this is a not a perk and can be reduced at any time

Legit, what the actual fuck???
