Tasty Tea has a highly talented workforce. Consequently, to appease their employees the company constructed a new lounge. The lounge has the capacity to accommodate at least 40 staff members at any point in time. For this reason, management believes that Tetley is the premier employer of choice. The entity commenced the year with a total of 2,800 employees, however, due to recession 50% of this complement was made voluntarily redundant during the year. This surprised senior managements because; at the start of the year they had anticipated for only 600 employees to leave. The excess was replaced immediately, by highly trained employees. The newly appointed employees had prior work experience from highly successful companies in the industry. Due to their work experiences, Tasty's profits before taxes increased by 14%. The profit increase resulted from efficiency gains due to increased productivity as a result of the company's time- based system Tasty uses an hourly based system with the aim of spurring productivity. This system pays a basic rate of $25 per hour and overtime depending on whether the staff worked during the evenings or on weekends.
