No it is not. All you need to prove work experience is a reference letter with all the required information and payslips if you have them.
"The following documents are
mandatory for each work experience declared:
a reference or experience letter from the employer, which
- should be an official document printed on company letterhead (must include the applicant’s name, the company’s contact information [address, telephone number and email address], and the name, title and signature of the immediate supervisor or personnel officer at the company),
- should indicate all positions held while employed at the company and must include the following details: job title, duties and responsibilities, job status (if current job), dates worked for the company, number of work hours per week and annual salary plus benefits"
