Job related expenses for a W-2 employee are not longer deductible since the TCJA of 2018.
If your employer reimburses you under an "accountable plan", then the amount reimbursed will not be included on your W-2 and you therefore can not deduct them.
If your employer reimburses you under a non-accountable plan, then the reimbursed amount is included on your W-2 and you "still" can not claim or deduct any expenses incurred as a W-2 employee.
